Explain, pls, in other words what she does, what is written in bold, and what exactly the word "self" here below means: "Story about Rock Star" Rock Star Amy Lee brings her goth girl self to the table and to the recording studio, no questions asked.
The question needs to be asked in the context of the idiom:
idiomatic expression: to bring something [here: her goth girl self] to the table
meaning: to have something to offer people in some situation.
A goth girl is a girl who dresses in the goth style.
goth girl self goes one step beyond that and suggests that a goth girl (or guy for that matter) not only dress in goth style but they have a personality [self] to match the attire.
It says her in the same way you would say her personality. It means it belongs to her and not to a general class of people.
